In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

This project controls a relay module using an Arduino, providing both automated timer-based operation and manual override functionality via a button. The system is designed for applications where a ...

Arduino has recently announced two new expansions to their Arduino Pro Opta PLC series – the Arduino Pro Opta Ext D1608E and Arduino Pro Opta Ext D1608S, the main difference between the two is that ...

An example of a simple way to command one (or several) Arduino relay(s) via a HTML & PHP web page. I did this for my student project. Please, note that the way to command the Arduino board over serial ...
